It features a radial leaded package with PCB mount installation. The component has a nominal resistance of 12 Ohms with a tolerance of 20%. It supports a continuous current rating of 5 A and a power rating of 5 W. The operating temperature range spans from -40°C to +200°C. Physical dimensions include a diameter of 24 mm, width of 7.5 mm, and lead spacing of 7.5 mm.

Inrush Current Limiters (ICL) Feature Summary

• Negative Temperature Coefficient behavior for inrush current suppression
• Radial leaded construction for printed circuit board mounting
• High thermal endurance up to 200°C maximum operating temperature

Inrush Current Limiters (ICL) Applications

• Inrush current limiting in power supplies
• Protection of electronic circuits against surge currents
• Temperature compensation in high-power devices

Inrush Current Limiters (ICL) Procurement Notes

Verify the specific suffix designation when ordering, as variants such as N20SP012M-F may exist with identical electrical characteristics but different packaging or marking standards. Confirm that the 5 A current rating and 5 W power dissipation align with the thermal management requirements of the target application. Ensure the 12 Ohm resistance value meets the circuit design specifications for effective inrush control.

Inrush Current Limiters (ICL) Selection Notes

Select this component based on the required steady-state resistance of 12 Ohms and the peak current handling capability of 5 A. The 24 mm diameter provides sufficient thermal mass for repeated surge events. Consider the radial lead spacing of 7.5 mm for PCB layout compatibility. The wide operating temperature range ensures reliability in harsh environments where temperatures may reach 200°C.

Inrush Current Limiters (ICL) Part Context

This part belongs to YAGEO's SP series of NTC thermistors, specialized for inrush current limiting. These components are engineered to provide low resistance at high temperatures after initial activation, minimizing power loss during normal operation while offering high resistance at cold start to limit surge currents.
